RNAV1

Garbling is caused by:

• aeroplanes transponder responding to sidelobes or reflections of the interrogation signal.

• aeroplanes in close proximity responding to the same interrogation.

• aeroplane at range responding to interrogations from another ATC, SSR.

• doppler effect on targets moving radially towards or away from the SSR.

Given magnetic heading 075°, variation 4°W, drift angle 12°R, relative bearing to the station 270°. What is the true bearing of the aircraft from the station?

• 169°

• 149°

• 173°

• 161°

The three main components of VOR airborne equipment are:

• receiver, phase comparator, range gate

• receiver, antenna, display

• display, pulse generator, phase comparator

• demodulator, antenna, CDU

Which of the following is the ICAO allocated frequency band for ADF receivers?

• 300-3,000 kHz.

• 255-455 kHz.

• 190-1,750 kHz.

• 200-2,000 kHz.

An aircraft is required to approach a VOR station via the 244° radial. In order to obtain correct sense indications the deviation indicator should be set to:

• 064° with the FROM flag showing.

• 064° with the TO flag showing.

• 244° with the FROM flag showing.

• 244° with the TO flag showing.

Which of the figures depicts an EFIS display in the Expanded (EXP) VOR/ILS mode with a VOR frequency selected?

• Figure 4.

• Figure 5.

• Figure 6.

• Figure 1.

What information concerning the aircraft's position can be determined from display 6 of the annex shown?

• Aircraft is left of the selected course and DME distance is increasing.

• Aircraft is left of the selected course and DME distance is decreasing.

• Aircraft is right of the selected course and DME distance is decreasing.

• Aircraft is right of the selected course and DME distance is increasing.

The meaning of the term 'GBAS' is:

• Ground Based Augmentation Systems.

• GPS Based Augmentation Standard.

• General Broadcast Application Systems.

• Ground Based Augmentation Software.

Which statement about VHF/UHF frequency propagation is correct?

• Neither VHF/UHF produces a skywave under any conditions. For VHF, the surface wave is the main propagation path, and for UHF, the space wave.

• VHF under normal conditions produces a skywave whereas UHF does not. For both VHF/UHF propagation, the space wave is the main propagation path.

• For both VHF/UHF propagations, the space wave is the only propagation path of practical use. There is no skywave under normal conditions.

• VHF frequencies below 120 MHz may be subject to sporadic E-reflections and which produces skywave. For both VHF/UHF, the skywave is the main propagation path of practical use.

In an ILS system, concerning the glide path principle of operation, the difference in depth of modulation (DDM): 1) Decrease with angular displacement below the glide path. 2) Increase with angular displacement above the glide path. 3) Decrease with angular displacement above the glide path. 4) Increase with angular displacement below the glide path. The combination regrouping all the correct statements is:

• 1,3

• 2,3

• 2,4

• 1,4
